My customer has run into what seems to be a general problem regarding the
network interface names.
They want to create an autoyast-based install of SLES11 on 100+ HP DL380 and
DL360 machines, which are all equipped with an extra interface card.
However Linux maps the logical interfaces depending on which of the internal
or the extra card that answer first during the installation. This mapping can
also differ from one OS installation to the next on the same box.

a) gets the current state of networking configuration at install time
(IP, gateway, active interface w/ MAC)
b) does a "sed" on the autoyast profile and substitute the proper
networking parameters
c) reload the profile
